Caught in the act
So, this apparently happened, and we can only guess what took place after this exchange of messages. Apparently, some person was messaging Lucy, presumably his boyfriend, asking what she was doing that night. Lucy says she was tired just chillaxing at home when in fact, according to the correspondence, she was at the club, since the original poster was standing right behind her.

Here’s something you could tell your boyfriend or girlfriend before heading out with the boys or girls. The truth. Seriously, they might have had a good time if they had gone out together, or if it was just ladies’ night, then maybe he would’ve backed off.
